Serial No. 157,555.

To all whom it may concern.

Be it known that I, hlausium. Henri PEARSON, a subject of the King of the United Kingdom of Great Britain and Ireland, residing at Leicester, in the county of Leicester, England, have invented certain new and useful Improvements in Eyeleting- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it upper tains to make and use the same.

The present invention relates to an improvement in eyeleting machines.

The objects of the present invention are to reorganize and improve the construction, organization and mode of operation of eyeleting machines, and especially the eyeleting machine illustrated and described in Letters Patent of the United States No. 683,488, October 1, 1901, granted upon the application of the present applicant.

To the above ends the present invention consists in the devices and combinations of devices hereinafter described and claimed.

In the accompanying drawings illustrating the preferred form of the present invention, Figure 1 is a. front elevation; Fig. 2 is a side elevation looking from the right-hand end of Fig. 1; Fig. 3 is a vertical section on the line m--;r, Fig. 2; Fig. 4 is a vertical section on the line 1 Fig. 2; Fig. 5 is a side elevation, with parts removed, of the punching and eyelet setting devices and the principal parts of their actuating mechanisms; Fig. (i is a perspective view of the punch and eyelet set support or feed frame; Fig. 7 is an enlarged elevation of the punch and eyelet set actuating cam and associated parts; Fig. 8 is a section on line Fig. 3, looking from the left; Fig. 9 is a section of the eyelet pot and associated parts on the line 10 w, Fig. 1; Fig. 10 is an enlarged detail of a portion of the punch and eyelet sct support or feed frame showing the punch and eyelet set and a portion of the actuating arm for the eyelet set; Fig. 11 is an elevation and Fig. 12 a side view of the die plate or anvil; Fig. 13 is a detail view showing the operating extremity of lever 7 5 in front elevation, and Fig. 14- is a detail view showing the form of the cam grooves in the cover plate 69.

The present machine, like the machine of the said patent, is organized and arranged to punch two holes in the opposite sides of. the upper of a shoe and then to set two eyelets in these holes and to feed the work.

The principal features of the present invention reside in the improved construction and organization of the machine. It will therefore be necessary in order to point out the features of the present invention to describe practically the complete machine in which the invention has been embodied, but before proceeding with a detailed description thereof the principal operative parts and their relation to each other and to the work will be pointed out.

The machine illustrated in the drawings has a frame N which incloses the principal operative parts of the machine, belng mounted upon a suitable base B to which it is secured in any desired manner. The frame N is provided with bearings for the main shaft M upon which are mounted the cams which actuate the operative parts of the machine. The main shaft is provided with a pulley by which it is driven from any suitable or convenient source of power, the pulley being revolubly mounted upon the shaft, and clutching mechanism, hereinafter to be described, is provided by which the pulley is clutched to the shaft.

The work is presented to the machine upon opposite sides of the guide plate G, the two sides of the upper being laid against the opposite sides of the guide plate with their edges against the edge guides carried by said plate. In presenting the work to the guides the clamping devices or work holders H are opened and after the Work is adjusted in correct position they are closed against the work to hold it in position in the machine. The machine is now set in motion and the punches P punch two holes in the opposite sides of the upper against the anvil or die plate A and then the punches are retracted from engagement with the material and the feed frame F is raised to bring the eyelet sets S opposite the holes just punched in the materials by the punches. The eyelet chutes G then present eyelets to the eyelet sets and withdraw, and the eyelet sets set the eyelets in the holes in the opposite sides of the upper against the anvil or die plate A. The feed frame F is then moved to the left from the position illustrated in Figs. 1 and 4 to feed the work rcarwardly the desired distance between two successive holes during which feed movement the work is held by the eye let sets S. the holders H being released during this time from engagement with the upper, the clamping devices or work holders again engage the materials, the eyelet sets are withdrawn from engagement with the materials, the feed frame returns to its original position, and the operations of the machine are repeated.

The guide plate G consists of a plate 1 against which the opposite sides of a shoe upper are laid with their edges against the edge uides 2 formed integral with or secured to the said guide plate 1. The shank 3of the guide plate is received in a vertical slot or groove 4 in a forwardly extended portion or overhang 5 of the frame N of the machine. The guide plate G is adjustable vertically in the groove 4 and adapted to be secured in any desired position therein by means of the screw 6 which is screwed through the block 7, being provided on its end with a spherical portion which engages a hole in the side of the shank 3 of the guide plate. The block 7 is loosely mounted in ears 8, projected from the overhang 5, one of said ears being graduated as shown in Fig. 1, and the block 7 being provided with a mark so that the block may be set to correspond with the various graduations of the ear. By turning the block in the ears 8 the guide plate G is raised and lowered and by tightening the screw 6 the guide plate may be set in adjusted position.

The guides 2 are projected beyond the edge of the guide plate 1 approximately to the center line joining the punches and sets so that the work may be accurately located with relation thereto, the projections of the guides extending on opposite sides of the anvil or die plate A. The guides 2 are each provided upon opposite sides with downwardly extended work guiding flaps similar in construction to those of the machine of the said patent and serving a similar purpose.

The work holders or clamping devices H are constructed and arranged substantially as in the machine of said patent except that their work holding ends 9 are extended down and rearwardly under the punches and dies so as to hold the work during the time the last holes at the extreme upper end of the upper are being punched or provided with eyelets. This feature, however, forms no part of the present invention as it forms a feature of United States Letters Patent No. 934,066 issued to United Shoe Machinery Company, assignee of George Goddu, on Sept. 14, 1909, to which reference may be had. The work holder arms 10, 11 are mounted upon shafts 12, 13, which are journaled in bearings in the shafts which carry the eyelet set actuating lovers. The arm 11, like the corresponding arm of the machine of the said patent, is provided with a rearwardly extending arm 14 carrying upon its end a cam roll which engages a ram surface 15 on the cam disk 16 mounted upon the main shaft of the machine. The arm 14 is provided with a rearwardiy extended projection 17 (see Fig. 2) which is engaged by one end of a lever 18 pivoted at 19 to the frame of the machine and actuated through suitable connections by a treadle when it is desired to open the holders to enter the work in the machine. The work holding arms 10, 11 are normally pressed against the work by means of the spring 19 in a manner similar to that illustrated in the said patent. The work holders H and the cam surface by which they are actuated. are organized so that they engage and hold the work against the guide plate G at all times during the operation of the machine, except during the time the work is being fed, at which time they are automatically lifted to free the work.

The feed frame F, which constitutes the support for the punches and eyelet sets, is provided with two rearwardly extended ears 20 through which a rod 21 passes, the rod extending outwardly beyond the ends of the ears 20 and receiving upon its outwardly extending portions two links 22 pivotally supported upon the rod 23 mounted in the overhang 5 of the machine. This arrangement is such that the feed frame may be moved up and down, the links 22 serving to guide the movements of its upper end, and constraining it, to move about the rod 23 as an axis. The rod 21 which passes through the ears 20 of the feed frame is embraced by the lower end of a link 24 which is extended upwardly therefrom to a crank pin 25 upon which its upper end is pivoted. The crank pin 25 has a tapered bearing in the upper end of the link 24 and is secured in the crank 26 mounted upon the front end of a shaft 27 mounted in bearings in the upper portion of the frame of the machine and adapted to be oscillated through 180 to raise and lower the feed frame. Upon the rear end of the shaft 27 is secured a pinion 28 which is engaged by a segmental gear 29 pivoted at 30 on the frame of the machine and carrying upon its lower end a cam roll which engages the cam path 31 in the cam disk 32 secured to the main shaft M of the machine. The above described arrangement is such that in timed relation to the movements of the other parts of the machine the feed frame is raised and lowered. The shaft 27 operates through a half revolution, thus moving the crank pin 25 from dead center above to dead center below the said shaft 27. This is a feature of the pres ent invention and contributes to the chiciency of the apparatus for actuating the feed frame in that the strains incident to the punching operation due to the downward thrust of the mechanism for actuating the levers 48 and 49 are resisted without tendency to rotate the shaft 27, which eonduccs to rigidity of the machine and the acmn'acy with Which the work is done. From the rear side of the feed frame are projected ears or lugs 33 which carry a vertical bar 34. This bar is mounted parallel to the plane including the axes of the punches and eye let sets. A block 35 is slidingly mounted on the bar 34 and journaled in arms 36 pivoted at 37 upon the frame of the machine. The arm 36 is secured to the arm 38 which is connected by means of a link 89 with the feed actuating and regulating mechanism. When the arm 38 is moved to the left of the position which it occupies in Fig. 4 it swings the arm 36 carrying the block 35 upward and moves it rearwardly, thereby moving the feed frame and feeding the work. It is to be observed that with the parts in the positions shown in Fig. 4, the line connect ing the axis of the block 35 with the pivot point 37 of the arm 36 is normal to the rod 34. The position of the parts as illustrated in this figure is that which they occupy after a hole has been punched in the materials and after the feed frame has been raised vertically to bring the eyelet sets opposite the holes punched in the materials. It will be observed that the feed frame may he raised at this time on the block 35 in the position shown and that the angular move ment of the feed frame in rising is very slight. In the machine of the said patent the lower part of the feed frame was directly connected to the link which moved the feed frame to feed the work and consequently when the feed frame was raised the lower part of the feed frame moved with more angular displacement than in the present instance. Furthermore when the block 35 is in the position shown in Fig. 4 the arm 36 is on dead center, that is normal to the bar 34, thus being in the best position which it could occupy to decrease the displacement of the feed frame during the punching and eyelet setting operations and contributing materially to the accuracy with which the punching and eyelet setting devices are presented to the work.

The feed actuating and regulating mechanism of the present application are essentially the same as in the machine of the said patent. The cam lever 40 from which the feed movements are derived is mounted in a bearing in the upper portion of the frame of the machine and at a point between its bearing and its end is provided with a cam roll which engages a cam path ll in the cam disk 42 mounted on the main shaft of the machine. The lower end of the cam lever 40 is connected to the link 43 which is connected to the link 3!) above referred to.

The punches and eyelet sols are arranged in the support or feed frame F in the sanic u'cncral lclflllcn to each othrr as in the said patent. that is. the punches are oppositely disposed to curb other and with relation to thc dic or anvil plate A. The punches are, however, positively operated in both directions, that is, they are positively actuated to engage and punch holes in the two layers of the upper and positively actuated to withdraw them from engagement with the upper. The cyclct sets are likewise ar- 1221l,?f(!(l to be actuated positively in both directions. The mechanism for actuating the punchcs has been modified from that illustrated in the said patent in order to relieve the punch and eyelet set cam of the very considerable pressure which was necessarily exerted by it in the patented construction. The punches l are each provided with a screw-threaded shank which is received in a screw-threaded hole in a punch slide 44 slidingly mounted in the lower part of the support or feed frame F. The punch slides ll are circular in cross-section and the punches are mounted in the lower parts of the punch slides. The punch slides are provided with holes 45 through which the pieces of material punched from the upper emerge. The punch slides are each provided with a transverse bearing l6 for pins 47. The ends of the pins 47 are reduced in size and secured to the lower ends of levers 48. '19. The levers 48. 49 are double levers and arc conneotcd by two similar links 50 at points intermediate their ends, said links 50 being located on opposite sides of the feed arm and pivoted to the levers 4d. 45) by means of pins 51. 52. The end of the pin 51 is eccentrically laced with relation to the body of the pin and the body of the pin is received in hearings in the lever 48. An arm 53 is secured to the pin 51 and is provided with a spring-controlled catch 54 which is adapted to engage the teeth of the segment 55 lixcd to the feed frame F. By moving the lever 53 up or down the pin 51 may be rotated in the levers 48 so as to regulate the movement of the punches. By lowering the lever 53 the punches will be moved toward each other and by raising it they will move away from each other, the catch 54 being adapted to hold the lever 53 in its adjusted position. A pin 56 passes through the uprr ends of the levers 48 and a pin 57 passes through the upper ends of the levers 49 affording pivots for the toggle links 60, 61. which are pivotally connected at their ends to the block 62. By raising the block 62 the toggle links, 60, 61 are straightened and the punches are brought toward each other. A link 63 is projected upward from the block ()2 and at its upper end it is pivotally attached to the yoke (34. The yoke 64 is suported upon a block (35 which is carried in a hearing in the end of an arm 66, hereinafter referred to, by which it is actuated from the main shaft. By raising and lowering the arm 66 the link (33 is raised and lowered, thereby raising and lowering the toggle block (32 and straightening and breaking the toggle formed by the links 60, 61, thereby forcing the punches toward and away from each other. The toggle block 62 is provided with a pin 67 which projects beyond each side of the block 62 being reduced in size at its ends and carrying cam rollers (38 thereon which are received in cam grooves in the opposite sides of the feed frame F. These cam grooves are formed in the cover plates 69 and the lower portions of said cam grooves are approximately the width of the cam rollers 68, but these cam grooves at their upper ends are widened as seen at 70, Figs. 6 and 14, to permit the block 2 to move laterally when it is in its raised position. Thus when the block 62 is lowered the punches are positively withdrawn by the breaking of the toggle and are positively retracted without capacity for movement or self adjustment, whereas when the block 69 is raised the cam rollers 68 move into a wide portion of the cam grooves, above referred to, and one punch is thereby permitted to advance farther than the other, thereby equalizing the pressure of the punches during the latter portions of their punching strokes, and affording freedom of movement to the punches during such time. This con truction compensates for variations in and equalizes the pressure which is exerted upon the punches bv the material, although the materials may be of different thicknesses. If it be assumed, for example, that the material on the one side of the upper were thicker than the material upon the opposite side, one of the punches would strike the thicker material first but it would not press heavily thereon until the other punch had been moved into contact with the thinner material upon the opposite side, when both punches would penetrate the materials with equal pressures thereon. This is important, because it equalizes the pressure of the punches upon the opposite sides of the anvil or die plate, thereby relieving the plate of undue strains thereon.

Before proceeding to a description of the devices which actuate the link 63 to operate the punches it is convenient to describe the eyelet sets and the anvil or die plate located between the opposing punches and sets. The eyelet sets consist of the setting dies 71 mounted upon slides 72 supported in bearings in the feed frame F below the bearings for the punch slides. The rear ends of the eyelet set slides 72 are provided with abutments 73 which are engaged by the operative ends of the eyelets set actuating levers T4, 75. The eyelet set slide 72 is hollow and receives therein a coiled spring 76 which presses upon the eyelet pin 77 and projects it forward through the eyelet die 71. The eyelet set slide 72 is provided with a groove 78 which is engaged by a latch 79 consisting of a hook shaped piece of metal having a head entering through a hole in the lower side of the feed frame F and being normally pressed in the direction to enter said hole by means of a spring 80 secured to said feed frame F. The groove 78 is provided with a vertical front edge and an inclined rear edge so that when the eyelet set slide 72 is moved forward the latch 79 is forced outward by the inclined edge of the notch. and when the eyelet set slide 72 is retracted the latch 79 slides down into the groove 78 and engages the vertical side of the groove and prevents the eyelet set slide 72 from being withdrawn beyond a predetermined distance. It is permissible, however, to withdraw the latch by hand and then, when the feed frame is lowered into position to punch holes in the upper, the eyelet sets may be withdrawn and others substituted therefor. The eyelet set actuating levers 7t and 75 are bell crank levers articulated together by their upper arms which are projected to ward each other. These bell crank levers carry on their depending arms lugs 81 which carry wear blocks 82 secured by means of bolts 83 in the lugs 81. The wear blocks 82 are sufficiently long to engage the eyelet sets at all times when the feed frame is in raised position. The extreme lower ends of the eyelet set actuating levers 74c and 75 are provided with hooks 84 which engage the rear faces of the abutment heads 73 of the eyelet sets when the feed frame has been raised and moved rearwardly to feed the work and when the levers 74 and 75 separate, the hooks positively withdraw the eyelet sets from engagement with the material. In the applicants prior machine illustrated in said patent, the eyelet. sets were withdrawn from engagement with the work by means of springs, and the applicant has found by his experience with the said machine, which is a high speed eyeleting machine such as is contemplated by the present invention, and especially as the work is fed by the eyelet sets while they are in engagement with the eyelets after having set them in the material, that it is highly desirable to withdraw the eyelet sets positively from engagement with the material before the return movement of the feed frame begins, so that by no possibility shall the eyelet sets or the eyelet pins of the sets be in engagement with the Work during such return movement of the feed frame. The hooks 8t, as shown in vl ig. l, are of less length than the wear blocks 82 so as not to interfere with the downward movement of the feed frame when in its forward position, and so that after the feed frame has made its return movement, thereby bringing the punches to their lowermost position below the wear blocks 0'2, the eyelet: sets may be withdrawn as above described.

The construction of the mechanism for actuating the punches is peculiar in that after the punches have made their punching stroke and been withdrawn from engagement with the material the distance which the downward movement of the link (33 inforccs, the lifting of the feed frame alters the position of the pivots 56 and 57 with re lation to the block 62, raising the pivots with relation to said block, and thereby further separating the punches with the lifting of the feed frame. After such lifting movement the parts occupy the position illustrated in Figs. 1, 2, l and hen the levers 74 and 7.3 are again advanced to operate the eyelet sets the punches are, of course, simultaneously advanced, but, owing to the fact that the feed frame has been lifted, the path of movement of the punches is so changed that the punches do not move far enough forward to engage the anvil or die plate,.or the upper edge of the materials, in case the eyelets are being set at such a distance from the edge of the work that the edge guides 2 are as high as or above the punches P as, for instance, if the edge guides Q occupy a position somewhat higher than that illustrated in Fig. 4. This is a feature of some importance in the machine of the present or similar construction in which the punches are actuated at the same time that the eyelet sets are actuated. In the machine of the said patent the punches are alternately actuated with relation to the actuations of the sets so that it is not neces sary to change the position of the path of motion of the punches while the sets are operated. In the present machine therefore, it will be observed that, when the punches are actuated to punch holes in the materials, the eyelet sets are not moved, the eyelet set actuating arms 74 and 75 making an idle movement at this time, but that when the eyelet sets are actuated the punches are also actuated butthe position of their paths of motion is altered so that the punches are prevented from coming in contact with the materials.

The bell crank levers 74 and 75, which have been described,as actuating the eyelet sets and as having their upper arms articulated together, are connected through the medium of the block 65 which is pivotally mounted in the forward end of the arm 66 of the lever 75. The block 65 is provided with a transverse hole which receives a rod 85 which is received within the bell crank lever 74. The end of the arm 66 is provided with a slot as shown at 87 in Fig. 4 through which the rod 85 moves during the rising and falling movements of arms 86 and 66. The eyelet set actuating levers 74 and 75 are. mounted upon or provided with hollow shafts 88, 89, received in bearings secured to or formed integral with the overhan 5. These hollow shafts 88 and 89 afford bearings forthe shafts 12 and 13 hereinbefore referred to as being the pivots of the clamping or work holding levers 10, 11. In order to separate the lovers 74 and 75 the clamping lever 10 is withdrawn by removing its shaft 12 from the bearing in the hollow shaft 88 when the rod 85 may be retracted withdrawing it from engagement with the block 65. The lever 75 is provided with an eccentrically mounted pin 90 which carries a cam roll 91 which engages a cam path 92 in the cam disk 16 hereinbefore referred to. By adj ustment of the eccentric pin 90 the )osition of the eyelet set actuating lever 75 wlth relation to the sets and punches may be varied in order to increase or diminish the pressure exerted upon the punches and sets. The cam path 92 is formed as has been stated in the cam disk 16. The cam disk is made of two parts, the one being the cam disk proper indicated by the reference character 16 and the other being the auxiliary or movable cam 93 which is mounted upon the cam disk 16 by means of a pivot 94 which passes through the cam 93 and screws into the cam disk 16. The cam disk 93 is provided with an elongated opening 95 which embraces the main shaft M of the machine so that said cam may move about the pivot 94 as a center with relation to the main shaft. Yielding means are provided normally acting to maintain the cam disk 93 in the position illustrated in Fig. 7 The cam 93 actuates the lever 75 both for actuating the punches and for actuating the eyelet sets. It is desired to actuate the punches positively, with capacity for equalizing their movements or the pressures exerted upon them by the material, and to actuate the sets yieldingly. The high portion 96 of the cam 93 may be referred to as the punching point of the cam and it operates the lever 75 to cause the punches to punch holes in the materials. After the punching point 96 has passed by the cam roll 91 the cam rotating as shown in Fig. 7 in the direction of the arrow 97, the lovers are withdrawn by the cam surface of the cam disk 16 after which there is a short dwell during which time the feed frame is raised to move the eyelet sets opposite the holes just punched in the material and to move the eyelet chutes forward to present eyelets to the sets, after which the eyelet sets are advanced a short distance to bring their pins into engagement with the eyelets presented by the eyelet chutes, this being accomplished by means of the portion 98 of the said cam 93 which may be referred to as the eyelet taking portion of the said cam, after which there is a further dwell during which time the eyelet chutes are moved back out of the way, after which the eyelet sets are advanced to set the eyelets in the materials by means of the portion 99 of the said cam 93, which may be referred to as the eyelet setting portion of the cam. After the eyelets have been set the eyelet sets are retracted slightly and then maintained in engagement with the eyelets during the time the feed is taking place, that is to say, dur ing the time that portion of the cam 93 marked 100 is passing the cam roll 91 which may conveniently be referred to as the feeding portion of the cam. It will be observed from the foregoing description of the cam 93 that during the time the punching point of the cam is passing the cam roll 91 the cam occupies the position illustrated in Fig. 7, its hole 95 bottoming against the shaft M while during the time the eyelet setting point of the cam is passing the said cam roll the cam is capable of yielding so that the sets are actuated with yielding pressure at this time. After the feed has taken place the cam drops off, thereby quickly retracting the sets from engagement with the materials after which there is a dwell on the cam during which the back feed or return movement of the feed frame takes place to bring the feed frame back to its original position. The yielding means for holding the cam 93 in the position illustrated in Fig. 7 consist of the bell crank lever 101 pivot-ed at 102 in a portion of the cam disk 16, one arm of which is projected into a hole in the cam 93 and the other arm of which projects through an opening in the main shaft M into the center of the shaft, where it is acted upon by a spring 103, the pressure of which upon the arm of the bell crank 101 is regulated by the adjustin screw 104 located in the central opening in the shaft M. By turning the adjusting screw 104 the pressure which the spring exerts upon the lever 101 may be regulated so that the cam 93 may be made to (yield under a greater or less pressure as esired. By these means the sets may yield with the thickness of work while setting eyelets but the punches are positively'actuated by the cam. An adjustable stop pin 105 is projected down through the overhang 5 in position to engage the end of the lever 66 when, in case the machine is running without setting eyelets, the lever rises, in order to prevent the eyelet sets from striking the eyelet setting die hereinafter referred to.

The anvil or die plate A is located between the oppositely disposed punches and eyelet sets and provided with a shank 106 which is grooved as shown in Figs. 11. and 12 so that it may be held in place in the feed frame by means of a pin extended through one side of the feed frame and engaging the groove. A punch block 107 and a setting die 108 are loosely mounted in holes in anvil or die plate A so that they may move laterally therein. The punch block and die are provided with transverse holes through which a pin 109 is extended through the hole 11.0 longitudinally formed in the anvil or die plate, the holes in said punch block and die being made larger than the pin 109 so that the punch block and setting die may have limited lateral movement in said anvil or die plate A. This permits the punch block and setting die to locate themselves with relation to the pressures exerted on them by the punches and sets. The present invention contemplates therefore a self adjusting anvil between the work engaging tools which is embodied in a self adjusting die block carried by the anvil. As illustrated, this feature of the invention includes a self adjusting punch block located between the punches and a self adjusting setting die located between the sets. This feature of the invention conduces to the equalizing of pressures upon the opposite sides of the anvil plate and on the opposite layers of work and in general to more perfect operation of the punches and sets.

In the machine of said patent the eyelet pot was set in an inclined position and delivered eyelets through combs on the lower side thereof to the raceways or eyelet chutes, and the eyelet pot was oscillated about a central line below the same, but it has been found that such construction was more or less objectionable owing to rapid running of the machine, and the present machine is equipped with an eyelet pot which delivers eyelets at its opposite ends to raceways or chutes through combs in the sides of the pot and the eyelet pot is mounted so as to oscillate about its own axis. This reduces the inertia of the pot and contributes to the ease with which it may be fed with eyelets. The eyelet pot 111 consists of a substantially cylindrical vessel with plane ends normal to the axis of the cylinder and having contracted body portions so as to direct the eyelets toward the ends of the vessel where they are discharged through combs into the eyelet chutes 112. The combs 113 are adjustably supported upon screws 114 which carry adjusting nuts 115 so that the combs may be moved toward or from the bases of the eyelet pot to allow for'thinner or thicker headed eyelets. A portion of the upper end of one side of each feed chute is pivotally attached to the eyelet pot and normally held in position by means of a spring catch which may be opened to dislodge any eyelets which T- secured.

may become lodged in the comb. The eyelet pot is supported upon an eyelet pot lever 116 which is provided upon its forward end with a disk 117 to which the eyelet pot is The front side of the disk 117 is transversely grooved and receives therein a transverse feather which projects rearwardly from the rear base of the pot. The feather [I8 is undercut at one of its ends and is projected under the hook 119 secured to the edge of the said disk 117 opposite the groove. The diametrically opposite edge of the disk 117 is notched at 120 to receive the locking bolt 121 which projects through the feather 118. The said locking bolt 121 is provided with a dog nut 122 upon its forward end. The eyelet pot lever 116 is mounted upon a hollow shaft 123 carried by bearings 124 and 125 in the frame. The hollow shaft 123 receives the brush actuating shaft 126 which is connected at its forward end by a tongue and groove connection with the brush shaft 127 mounted in bearings in the bases of the eyelet pot 111. The shaft 127 carries brushes which sweep the eyelets past the combs so as to deliver them therethrough to the eyelet chutes. The brush actuating shaft 126 is provided upon its rear end with an enlargement 128 which is grooved at 129 and in such groove are located a plurality of balls 130 which project beyond the groove in the cavities in the collar 131 by means of which the shaft 126 may be clutched to the collar 131. The rear end of the brush actuating shaft 126 is provided with a handle 132 by means of which the shaft may be moved rearwardly against the action of the spring 133 to disengage the tongue and groove connection between the shaft 126 and the shaft 127. The collar 131 is connected by means of a link 134 with the upwardly projected arm 135 secured to the cam lever 40, thus during the operation of the machine the brushes are intermittently advanced during portions of the revolution by the means described. lVhen it is desired to remove the eyelet pot from the machine, the dog nut 122 is loosened and the eyelet brush actuating shaft 126 is moved rearwardly whereupon the eyelet pot may be slid to the right as viewed in Fig. 1, thereby releasing it from engagement with the disk 117 of the eyelet pot actuating lever 116. The eyelet pot actuating lever 1.16 is provided with a downwardly extended portion 136 which carries a cam roll which engages the cam surface 137 of the cam disk 16. A spring, not shown, normally holds the cam roll in contact with the cam disk and means somewhat similar to those employed in the machine of said patent are provided for catching and holding the said arm 136 from contact with cam when it is desired to punch holes in the work without setting eyelets therein. The latch 138 is employed for this purpose being connected to the feed regulating mechanism.

In connection with the eyelet pot there is employed an eyelet supply device for supplying eyelets to the eyelet pot. This eyelet supplying device consists of a vessel mounted upon the upper part of the frame of the machine and. having a nose or spout projected forwardly over an opening in the upper part of the eyelet pot. The lower surface of the nose of the eyelet supply vessel is cylindrical and fits the corresponding cylindrical surface of the eyelet pot. It is apparent therefore that oscillations of the eyelet pot do not interfere with the close fit of the nose thereon and that at any time during the operation of the machine the operator may reach into the larger part of the eyelet supply vessel and draw forward some eyelets so that they may flow down through the nose of the vessel into the eye let pot.

The features of the present invention, just described, relating to the mechanism for supplying and delivering eyelets are not claimed herein as such features are claimed in a divisional application Serial No. 607,159, filed Feb. 7, 1911.

A clutch mechanism is employed for connecting and disconnecting the pulley 139 to and from the main shaft M of the machine. It is important in operating eyeleting machines that the machine should always stop with the parts in position to remove and enter the work and to this end various clutch mechanisms may be employed to connect and disconnect the pulley from the main shaft of the machine.

The clutch mechanism illustrated in the drawings which has been found to be particularly useful in operating this machine is described as fdllows :--As has been stated the pulley 139 is provided with a bearing 140 which is loosely mounted upon the reduced end 141 of the main shaft M of the machine, being secured in place by means of a washer 142 and set nut 143. A friction disk 144 is mounted upon the main shaft and the opposite sides of its periphery are adapted to engage respectively the friction surface 145 mounted on the pulley139 and the friction surface 146 mounted upon a plate 147 secured to the frame of the machine. The friction disk 144 is provided with a sleeve 148 which is mounted upon the main shaft M so as to be capable of sliding endwise thereon but held from rotation with relation thereto by means of a pin 149 which passes through the main shaft and engages a slot 150 in the said sleeve 148. The pin 149 passes through a slot in the main shaft and is capable of being moved longitudinally of the main shaft by means of the screw 151. When the screw 151 is screwed somewhat beyond the position in which it is shown in Fig. 3 it moves the pin 149 to the right of the position shown in Fig. 3 so that its ends engage the ends of the said slots 150, thereby moving the sleeve 148 which carries the friction disk 1.44 to the right so that the disk cannot come in contact with the friction surface 145 secured to the pulley 139. This is useful for the purpose of moving the friction disk 144 so that the machine cannot be started by power, but may be operated by the hand wheel. 152 for the purpose of adjustment or otherwise. Means are provided for moving the friction wheel 144 longitudinally of the shaft to throw it into engagement with the friction surface 145 of the pulley or the friction surface 146 secured to the frame of the machine, and such means consist of the following devices :For the purpose of moving the sleeve 148 carrying the friction disk 144 toward the left in order to throw the friction disk 144 into contact with the friction surface 145 of the pulley, a sleeve 153 is provided which is screw-threaded on a reduced portion of the sleeve 148 and can ries springs 154 in spring pockets therein which engage the surface of the cam disk 32 hereinbefore referred to, fixed upon the main shaft of the machine, and normally tend to move the friction disk 144: into the position illustrated in Fig. 3. A ring 155 fixed to the frame of the machine embraces the outer surface of a portion of the sleeve 148 and affords a bearing therefor. This ring 155 is provided with inclined teeth 156 which cotiperate with similar teeth 157 upon a ring 158 which is loosely mounted in a bearing in the frame of the machine (see Fig. 8). The ring 158 is capable of oscillating through narrow limits less in extent than the length of one of the teeth 156 and 157, so that the teeth do not pass each other, and such oscillation of the ring 158 operates, when moved from the position illustrated in Fig. 3. to slide the teeth 157 up on the teeth 156 so as to move the ring 158 and the sleeve 148 toward the right as shown in Fig. 3, thereby pulling the fric tion disk 144 out of contact with the friction surface 145 and into contact with the friction surface 146 secured on the frame of the machine.

Inside of the ring 158 is located an eccentric strap 159 which embraces and is actu ated by eccentric portion 160 of the sleeve 148. An arm 161 projects outwardly through a hole in the ring 158 and enters a pivot block 162 mounted in a bearing in the frame of the machine so as to prevent rota.- tion of the eccentric strap. The lower side of the eccentric strap 159 is provided with a tooth 163 and the eccentric movement of the said strap 159 moves the tooth through an elliptical path. Pivotally mounted upon the said ring 158 is a dog 164 which is adapted to be engaged by tooth 163 when the dog is in its raised position and the tooth is traversing the lower part of its path of motion. When the dog is held down by the link 165 which runs to a treadle, not shown, the tooth 163 does not engage the dog 164, but when the dog 164 is permitted to be raised by a spring, not shown, it is brought into the path of movement of the said. tooth 163 and upon its next forward movement the tooth 163 engages the dog and moves the ring 158, causing the teeth 157 to slide up on the teeth 156, thereby forcing the sleeve 148 to the right of the position shown in Fig. 3 to unclutch the main shaft from the pulley and bring it against the friction surface on the frame of the machine. By depressing the treadle and disengaging the dog 164 from the tooth 163 the machine is set in operation, and by removing the pressure on the treadle the machine comes to rest, and during the operation of the machine the treadle must be held depressed to hold the dog out of engagement with the tooth 163. This clutch mechanism forms no part of the present invention and is illustrated and described in this specification merely for the purpose of describing the complete machine in which the invention is preferably embodied.

Certain features of the present invention are not limited to use in a machine for setting eyelets in both sides of the upper of a shoe but may be employed in connection with a single eyeletting machine.

The operation of the machine has been set forth in connection with the description of the construction of the machine.

The present machine, like the machine of the said patent, is constructed and adapted primarily for the purpose of punching holes in the opposite side of a shoe upper and setting eyelets therein, and the machine is further adapted, when desired, to throw the eyelet feeding mechanism out of operation so that the machine may be employed simply for punching holes in the leather, as in mens work in which eyelets are set in the lower part of the lacing slit and holes are punched in the upper part of the upper to receive lacing books.

It is within the purview of the present invention to substitute hook setting devices for eyelet setting devices so that the machine may be used for punching holes in the material and setting lacing hooks therein, such necessary changes being made as would be required to adapt the machine to such work.
